Re: [PATCH] t7403-*.sh: Avoid use of the nonportable '==' operator

Thanks.  You do not have to single-out dash.
A shell script that uses "test $a == $b" is *buggy* and not conforming to
POSIX.

Yep. This slipped through because I happen to have reconfigured my
/bin/sh to point to bash (frrom Ubuntu's default of dash) because of
an issue with a product installation script. This shouldn't have been
a problem if bash's POSIX mode was strict about rejecting == but bash
doesn't seem to be strict about this.

Anyway, I have reverted /bin/sh to refer to dash so hopefully I won't
be caught by this in future.
